Boolean operator gmsh

So, as the error says, the mesh of quadrilateral elements that you have created cannot be ordered in a consistent way (this issue is related to: Unable to order quadrilateral cell)
which lead to the paper by @mscroggs : https://dl.acm.org/doi/full/10.1145/3524456 (arxiv version: [2102.11901] Construction of arbitrary order finite element degree-of-freedom maps on polygonal and polyhedral cell meshes) which has been implemented in DOLFINx.
